Since 2007, YSL have been working with photographers nez van Lamsweerde and Vinoodh Matadin, and have been pairing them up with a new supermodel each season. First Gisele Bundchen, then Kate Moss last Spring, then Naomi Campbell, followed by Claudia Schiffer this Spring, and now we have the age-defying, ever-beautiful Christy Turlington.

More after the jump.
